Drainage geonet, also called Composite Geonet, is a two or three-layer three-dimensional drainage geosynthetic product which are often made with polypropylene PP or regenerated HDPE (called geonet) and covered with single- or double-sided thermally heat-bonded nonwoven geotextile on both sides or one side.
The geonet has high drainage performance which is made of high quality polyethylene resin, adding 2-3% carbon black, anti-UV and anti-oxidant processed by special extruding technology. Nuolian brand drainage net has excellent performance than traditional draining gravel. The 3D composite drainage net combines the characteristics and functions of geonet and geotextile, it has the comprehensive charateristics of anti-filtration, good drainage, air permeability and high strengthen and protection reinforcement. It is an ideal new drainage geo material.
